Aerial images in the vicinity of USGS gaging station #07094500 Arkansas River at Parkdale, Colorado were collected on March 20-22, 2018, using Unmanned Aircraft Systems (UAS, or "drones"). Data were processed using structure-from-motion analysis to generate a three-dimensional point cloud that identifies pixels from multiple images representing the same object and calculates the x, y, and z coordinates of that object/pixel. The point cloud was processed to create a digital surface model of the site. Finally, source images were stitched together based on shared pixels and orthogonally adjusted to create a high resolution (approximately 2 cm pixel size) orthoimage for the study area. The orthomosaic image captures...

The Hydrologic Remote Sensing Branch (HRSB) community is intended to host remote sensing technology datasets and information products to help WMA and Water Science Center (WSC) staff more safely and effectively gage streams, monitor water quality, and measure the hydrologic cycle.
|
This Science Base Community is a home for data collected by unmanned aircraft systems (UAS) or drones and from non-contact sensors on fixed-mount and near-field platforms such as bridges, for water related projects. The goal is to make it easier to publish remotely sensed hydrologic data and create a collection of remotely sensed hydrologic data sets.
